Lines And Angles One Shot With Ushank Sir | Science and Fun 9th Class 

33:16 in line AB BY (LPA) LINEAR PAIR OF ANGLE = 180°

33:15 there are 2 ways to find it 1) in a triangle sum of all angles is 180 90 + 36 + x = 180 126 + x = 180 x = 180-126 = 54 2) Angles on straight line x + 36 + 90 = 180 x + 126 = 180 x = 180 - 126 x = 54

Angle AGE+angle FGE =180°(linear pair) angle AGE=126° angle FGE=180°-126°=54°

36:53 angle QRS=60 degree Angle QRA+QRS+SRB=180 degree Then angle SRB=60 degree sit

33:15 angle FGE+ angle AGE=180 [linear pair] FGE=180-126 FGE=54

Lgta ha aashu sir ne apne jaise dikhne wale logon ko hi lia ha....🤣😅😅😅💀

All the best for tomorrow's exam👍

22:41 angleXYQ=122° angle QYP=58° reflex QYP=302°

29:39 ANGLE AGE=angleGED(alternate interior angle) Angle GEF=126°-angleGED(90°)=36° Angle FGE=54°(180°-Angle AGE(126°)(Linear pair angles))

Angle PRQ+45°+70°=180°(Angle sum property) PRQ+115°=180° PRQ=180°- 115° PRQ=65°.... OR Angle PRQ=110°- 45°(exterior angle property) PRQ=65°

35:59 Sir we can also find it out as angle TSR is equal to angle SRA and angle QRA is 70 degress so angle QRS will be equal to 130 degrees - 70 degrees so angle QRS will come out to be 60 degrees

Angle FGE is of 54 degree (linear pair)

angle AGF is 180 degree, to find FGE, 180-126 (ANGLES ON STRAIGHT LINE) 54 DEGREE

Ang. AGE + Ang. FGE = 180(angles on a straight line) 126+ ang. FGE = 180 ang. FGE = 54

32:50

36:23 to find angle QRS ARQ+QRS+SRB=180` { angle on straight line} 70+QRS+50=180 QRS=60degree

You are amazing sir. I solve tough to tough questions in a very simple and easy way. 😊

ans is 54....... alternate interior angles....... heart and star and likes

32:59

Aaj Tak jab se 9th me aaya hu math nahi samajh aai lekin jab sir aap se padha to sab samajh aane laga grear🎉🎉

Kl paper hai and I just watch this video 📹 and all my concepts were done ✔️ thanku ❤️ so much fir this powerful video 😊

6:38 angle1=angle5 angle2= angle6 angle3= angle7 angle4= angle8

Sir Angle QRS = 70°+50°+QRS=180°(angles on straight line) 120°+QRS=180° QRS=60°

Your explanation is best sir All maths teachers should be like you

33:11 it will come from linear pair 180° - 126° = 54° Answer

32:56 age + fge =180 [linear pair] =126+fge=180 =fge=180-126 fge=54

33:00 180-126 = 54⁰

33:10 Answer is 54 degree because a to b = 180degree and 180-126=54degree by straight angle

54° because of linear pair identity 33:17

32:56 AGE+FGE=180(angles on line) 126+FGE=180 FGE=54

ANGLE FGE+ ANGLE GED=180 ANGLE FGE+126=180 ANGLE FGE=180-126=54 ANGLE FGE=54

Important note: 5:45 in this no need to write for reason like (angles on straight lines ) u can write is as (linear pair axiom) easyy

03:09 Sir doubt

Thnks sir apne bht imp questions karari 🎉🎉 like kardobisbbstoe 😅

33:08 54 linear pair

33;10 Angle FGE=54' (.,.Linear pair )

32:47 Question he asked AGE + FGE = 180 (alt. Interior angle) 126 + FGE = 180 FGE=180-126 FGE=54

32:50 180 - 126 = 54

36 beacause of vertical opposite angle

32:57 54°

36:21

33:16 FGE=54(Linear Pair )

The bell rings in 11:16 hear it carefully and again in 38:47

LCEG + LGEF + LFED = 180° (ANGLES ON STRAIGHT LINE) LCEG + 36° + 90° = 180° LCEG + 126° = 180° LCEG = 180-126 LCEG = 54° PROOF LFGE LCEG = LFGE (ALTERNATE INTERIOR ANGLE) LFGE = 54° PROOF LAGE LAGE=LGED. (ALTERNATE INTERIOR ANGLE) LAGE = 126° LCEG

13:10 reflex is equal to 360-(ANGLE x)

Sir 54 degree because those angles are forming linear pair on a straight line so, the sum of two angles on a straight line is 180 degree and 180-126 we get 54

19:45 Sir iss question me hamare teacher ne aisa sikhaya hai In angle SOQ AngleSOQ= angle SOR+ angle ROS----------> (1) In angle POR Angle POR= Angle SOR + POS------------> (2) Adding (1) nd (2) Angle SOQ + angle POR= 2angle SOR +angle ROQ + angle POS Angle SOQ+90°= 2angke SOR + 90° + POS SOQ=2SOR or ROS+ POS (90° is cut) 2ROS=SOQ - POS ( turning LHS nd RHS) ROS=½(SOQ-POS) It was kinda difficult but i somehow leatned it ❤️

Excellent explanation... you deserve more subscribers! ❤

Angle FGE =180°-126° =54°

Sir aap online class lete hai fees kitni hai sir I want to join sir please tell.😊😊

thanks sir for the lecture today hw angle FGE +angle GED= 180 (CO INTERIOR ANGLE ) angle FGE = 180-angle GED angle FGE = 180- 126 = 54

Angel fge 54 +126 equal 180 linear pair

32:50 angle AGE + angle FGE =180....(linear pair) . 126 + angle FGE = 180 degrees . angle FGE = 180 - 126 degrees . angle FGE = 54 degrees

33:02 angle AGE + angle FGE = 180 (linear pair) 126 + angle FGE = 180 angle FGE = 180 -- 126 so, angle FGE = 56

33:11 the ans will be 54° Proof:- on a line CED= 180°-126° =54°(L AEC) So, L AGF=L AEC (54°) (alt int angles) L AGF=54° H.P✓

Line - Which has no end point Line segment - PART OF A LINE WHICH HAVE 2 END POINT RAY PART OF A LINE WHICH HAVE 1 END POINT

Amazing teacher👏👏👏👏👏👏

Doubt :Sir 4th question ka answer scl walo ka kuch alag hai aapka alag hai hmm aapke wale trike se b krrr skte hai na plzz reply ❤aapke trika bhot easy hai ❤

Thank you sir. This video was very helpful for me ❤❤

33:08 angle FGE=54degree

Explanation has been done well done ❤

Angle FGE + Angle AGE=180°(linear pair) Therefore Angle FGE = 54°

I was unable to understand maths in my class but u helped me alot thanks sirr ❤️🙏

Angle FGE IS 54 DEGREE because of linear pair with AGE 180-126=54

54 linear pair se queston at 33:15

37:19 y=80°,x=50°.

need more teachers like you sir🤠🤠🤠

Linear pair =180 126+54=180

I fully understand how much you have teach

33:21 Contruction(draw AB parallel to PQ) AngleSRB+TSR(130°)=180°(co-interior angles) AngleSRB=50° IIILY AngleQRA=70° And angleQRS+QRA(70+SRB(50)=180°(anle on straight line) So angle QRS=60°[180-(70+50)] SO LENGTHY

Sar aap bahut Achcha padhaate Ho❤🎉😊

Thank you sir I was not understanding the angles that alt.int.angles..........

27:22 = alternate interior angle

Angle FGE = 54° ( angles on straight line )

180-126=54 region linear pair🎉🎉🎉😊

=> Angle AGE + FGE = 180° => Angle 126° + FGE = 180° => Angle FGE = 180° - 126° => Angle FGE = 54° (Edit : I am write and wrong hmm 🤔)

1 ans 54 2 ans 60 (angle on straight line)

33:08 54• linear pair

QRS +QRA +TSR =180 QRS + 70+ 50= 180 QRS= 180-70-50=60 QRS =60

Angle BOE=40,reflex=250

Sir 11:16 par ghar kon aaya tha aapke 😅😅😅😅

thanks for your best teaching

Sir you are the best teacher because I am not understand math but after watching your videos I understand very well thanks sir

Good evening sir.. Sir Angle FGE linear pair se 54 aega.. agar mera answer thik h to like kr dijiye or agr nhi h to ap bta dijiye ki kya mistake h

Given - AB PARALLEL TO CD EF PERPENDICULAR TO CD AND ANGLE GED=126° GED=GEF +FGE 126=GEF+90° GEF=126-90 GEF=36 AGE=GED(ALT INT ANGLES) FGE+AGE=180°(LINEAR PAIR) FGE=180-126 FGE=54° SO AGE=126 GEF=36 FGE=54 Hence proved

Thank you very much sir because from tomorrow my half yearly are starts and I have so many confusions in this chapter. Thanks a lot sir❤

180-126=54 (linear pair)

My all the concepts are clear now. This video is very very helpful for exam point of view . There are 3 questions in my exam from this video

36:19 angle QRS is equal to 60degree

Sir 54 because ab CD are equal

FGE 54 and because AGF straight angle 180-126. 54

33:15 sir 📐FGE linear pair answer is 180- 126 = 54 😃

G=180-126=54(linear pair)

Angle BAC is forming alternate angle 41:34 as it forms z

33:10 Ans of this is 54 ais sum of straight line angle is 180.😊😊

33:01 ans

ANGLE(AGE+FGE) =180 DEGREE [ ASL] 126+ ANGLE FGE =180 DEGREE ANGLE FGE=180-126 ANGLE FGE=54 DEGREE

angleAGE+angleFGE=180degree [ by linear pair ] 126degree+angleFGE=180degree angleFGE=180-126 angleFGE=54degree

Best teacher of the year in math 🎉🎉🎉🎉🎉🎉❤❤❤❤❤❤😊😊😊😊😊😊😊😊
